Not to be confused with the infamous serial-killer from London, the murderer larva is just a DVD changer. One Raspberry Pi fan was uninterested in manually dynamic  out discs whereas splitting DVDs to store content digitally.

The machine uses 3D-printed components to tug CDs out of the player, drop them off to the aspect, and so load during a new one.  Of course, it's power-driven by a Raspberry Pi.
